You got 'em in right, Mark.

Dave, take a look at the empellor swirl fins. Does it look like Ive got them in backwards?

[crazygary]

Whatever floats your log....Err! Boat!! Yeah, that's it!!! Hah!!

Its not everyday you meet someone willing to blast pictures of his bathroom all over the free world...................and then some.

Now on to the process by which I am trying to reduce the vibrations affecting the APC. I took a shipping envelope that has the bubble wrap applied to the inside. From it ,I cut a large piece and siliconed it down to the equipment tray. Then I took the APC and did likewise. When it drys it will be attached and floating on top of the air bubbles.

Now on to the Hydrostatic pressure chamber test tank. Please note all the scientific equipment clearly in evidence and the numerous Diplomas casually displayed about the area.

[greenman407]

Moving right along here,...............I just had an epiphany. Take out the old ball and nylon clasp links and put in some double Klikons. Yeah,....thats what Im talkin about. Reaching down into the small confines of a Seaview interior and wrestling with those things....nope nope nope, not any more. I also took a couple of pieces of alluminum square tubing and cut out one side and CAed them under the styrofoam support mount to capture the pushrod so that If it popped loose it would still link back up.

[crazygary]

Very cool, Sir!!

Git 'er done!! Hah!!

Got the BEC installed today.It wont be long now. Ill be testing this thing at the Clearwater pond next week for sure.

[greenman407]

Install of the power wire harness. Ill finish it all as soon as the BEC gets here.Perhaps you can see here the servo mount that I made that reaches up and cradles the tops of the motors. In the floor of the aluminum equipment tray I drilled holes as well as through the uprights of the plastic servo mounts. By using "Goop" to attach the servos to the mounts, the "Goop" seeped through the holes and formed a rivet head on the back side as well as through the floor. After it cured, its rock hard, providing plenty of support to make the whole assm. solid.

Because I am using two speed controllers, I needed to get power to them, so I made up a harness with bullet connectors. These solderless connectors can be soldered, you just have to cut of the hard plastic insulator material that surrounds them. I thought that they were alluminum but touch them with a Dremel and the outer plating comes off, revealing the copper underneath. Using paste flux and rosin core solder and a really good HOT gun , causes the soldering to take just seconds per joint. The only bad thing is that on the bullet connectors, the insulation that I left on it to shield the female part of the connectors, shrunk with the heat of soldering, squeezing the connector, not allowing the male to connect. So I split it up one side and am saving the piece to install back on after the connection is made.

I got my two speed controls in so.............what am I waiting for? Idunno. Ive got a sneaking suspicion that after sea trials, Im going to end up going to 2:1 gear reduction. I can just somehow.......sense these things.

I find the best thing to shape foam with is some 120 grit sand paper glued to a block of wood. For concave curves I use a piece of dowel (broom handle etc) with the paper glued to it. I also have a HF Sander which is ideal for rounding off corners.

[greenman407]

Using a straight edge and marker, I mark it out. Using a long sharp xacto knife and a pulling towards you motion, I cut the piece out of the foam sheet. Then I mark what needs to be cut out for clearance using, once again the long Xacto to mark its edges, then I cut out between the lines with a Dremel endmill thats about 3/8" in diameter and that has cutting edges on the end of it.
If it ends up that Ive got too much foam in there, I just bring my Xacto with me to the lake and trim out a slice or two from the end of the uppermost piece until it floats like I want.
If its not enough foam then I always bring some extra pieces with me and try various ones by sticking it under the hull till it floats it and I find the right combination.

Excellent! What is your way of shaping the foam? Like the channels?
